We all fall into one of the following categories when it comes to our health and fitness, it can change over time but it's good to know which one you are currently in.
So which are you? A good thing to do is to identify what your ideal standards are for yourself: How do you want to feel, how strong would you like to be, what's your ideal weight, how would you like your body to look? ect. It's good to get specific, and also realistic. For me I know the bodyweight I feel best at, I know how much weight I should be able to lift without too much difficulty, and I know how long I can go for a run, row, or bike ride without getting super gassed. So for me I am more in the maintenance category, if I notice I am slipping somewhere, I make some slight adjustments. If you're just starting out, just start with one goal or standard you want to shoot for, otherwise it's too much, then work on the next thing. Remember to be consistent and little by little you'll get there.
